- I anuento; Fi i flamzmy 'UNl t-lAlEld Application filed March 5,

To all whom it may concern:

Be it known that I, PARLIN H. Cannwar, a citizen of the United States of America, residing at l-Vetappo, in the county of Vl asliington and State of Florida, have invented new and useful Improvements in Lubricators, of which the following is a specificati resent invention relates to improve n are in lubricators and has particular apntion to sight feed lubricators.

in carrying out this invention, it is my purpose to provide a lubrieator of this type which shall be'constructed in such manner as to prevent dirt, dust, grit and other foreign substances being conveyed with the lubricant to the machinery.

It is also my purpose to provide a lubricator wherein the quantity of outl'lowing lubricant may be viewed with facility, the lubricator involving a transparent reservoir or oil chamber for this purpose. Furthermore, I aim to provide a lubricator wherein the grit, dust, and other foreign matter will be trapped or caught previous to the discharge of the lubricant from the reservoir.

With the above and other objects in view the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the appended claims.

In the accompanying drawing wherein has been. illustraleo one embodiment of my invention; Figure 1 is a side elevation of a lubricator constructed in accordance with the present invention. Fig. 2 is a central vertical sectional view thereof.

Similar reference characters designate like parts throughout the several views.

Referring now to the accompanying drawin g in detail, the lubricator embodies a reservoir or lubricant container 1 constructed of glass or other suitable transparent material, the reservoir in the present instance, having a lower frusto-conical shaped portion 2 and an upper semi-spherical portion 3. Formed in the upper portion 8 and centrally thereof is an opening 4 provided with an upstanding neck 4; and designed to receive a valve tube 5 threaded interiorly, as shown, and in which is arranged the stem 6 of a needle valve 7, the tube 5 terminating at its lower end within the reservoir in a contracted dis charge orifice 8 designed. topermit the flow of oil from the reservoir and controlled by and held in engrr 1912. Serial l lo. llflllfi'w.

means o'l the needle cured to the outer oi is a hand wheel 5 opening and closing 0'. ran d co; ice utrically trenuty at the valve stem 6 10 adapted to so went with the melt such opening by means oil an eatpansimi spring Ill. coiled about the stem i1itorrnediate the hand wheel and the cover. Embracing the neck 4t is a strap 12 equipped with spring finger 13 designed to engage the h an wheel 9 of the valve stem to prevent a dental movement thereefo 'lhreaded onto thelower end of the valve tube 5 and within the lower portion of the reservoir is a sleeve 14: provided with a sight aperture 15 and inhlosing a transparent tube 16 of glass or other suitable materialwvliieli tube forms a sight-window for the lubrieator, and threaded into the lower end of'the tun: 14C is a short section. of piping lF-terminatin' enteriorly of the reservoir as at 18 and pie vided with screw threads so that the lubr. cater may be attached to the mechanism. f be lubricated, the short section of piping l. ingorovided with'a non-circular boss ll) accommodate a wreneh'or other suitable tool. i'i'loun'ted upon the pipe '17 above the boss is, are a plurality of clamping nuts l0 designed to engage the upper and. low r s facesof the bottom walloitametallics-up This'cup 22, in the presmt instance, is pro vided with a substantially circular vertical. wall equipped atits open end with rowing fingers 24- adapted to ei'nbraoe an :uuu hi head 25 formed on the exterior surface at the lower portion 2 of the reservoir 1 so as to securely hold the reservoir or lul'nicant coutainer in position. Formed in the valve tube 5 are a plurality of oil passages 26'. ill commuuicating with the interior or such tube and with oueanother by way of a duct 27 so that in the opening oi? the needle valve, L the oil may be disclnnrtg'ed from the l fll'- voir to the mechanism to be lulu-icated, y way of the sight glass and piping l7. Thus, it will be seen that the lower portion of the reservoir, below the sight wii'ulo'w forms a trap for any foreign material that may have entered the reservoir with the lubricant thereby preventing the discharge of such n'm'terial with oil. If desired, the lower unliion oil the servoir may be filled :5

with water or the like oil-floating medium to a point adjacent the lower oil inlet 26 of the valve tube. Such oil floating medium is not necessary, howev-zu', as the lower part of the body of oil or other lubricant within the reservoir may be utilized for the same purpose. Furthermore, it will be noted that the feeding of the oil may be readily determined or viewed through the reservoir, the body of fluid within the bottom thereof and the sight window, the reservoir being constructed of transparent material for this purpose.

'From the above description taken in connection with the accompanying drawing, the construction and mode of operation, as well as the advantages of my invention will be readily apparent, and while I have herein shown and described one particular form of my invention, by way of illustration, it is to be understood that I do not limit myself to all of the details of constrmztion herein described and delineated, as modification and variation may be made without exceeding the scope of the claims ordeparting from the spit'it of the invei'ition.

I claim:

1. A lubricatilr comprising a reservoir formed oftransparent i'nalerial and adapted to contain a quantity of lubricating mate- 'rial, a sight; tube within said reservoir, and a trap i'ori'ned by the lower part of said reser w n r.

,2. A lubricator comprising a reservoir forn'ied of transparent material and adapted to .(1 ntain a quantity of lubricating mate rial, a sight tube Within said reservoir and in communication therewith, means controlling the communication between said sight tube and reservoir, and a trap formed by the lower portion of said reservoir adjaeent the sight tube therein.

A lubricator comprising a trans 'iarent. reservoir formed with a frusto-conical bottom portion and a semicircular top portion, said top portion being provided with a centrally arranged opening, a neck projecting upwardly from said top portion concentrically of the opening therein, a valve tube arranged within the opening and depending into the reservoir, a valve within said tube and provided with a stem projecting outwardly of the reservoir, a hand wheel upon the stem, a cover plate upon the stem and inclosing the opening in the upper portion of the reservoir, a spring encircling the stem intermediate the hand wheel and cover plate, means carried by the said neck and in engagement with the hand wheel to prevent accidental turning i'novement thereof, and a sight tube within the reservoir and adapted to have communication therewith.

4. A lubricator comprising a reservoir, a valve within the reservoir,a sight tube within the reservoir and adapted to have (,Olllll'llllllcation therewith by means of said valve, a discharge pipe in connnunicat-ion with the sight tube and extending outwardly of the reservoir, a cup carried by said pipe and adapted to receive the lower portion of the reservoir, and a trap formed by the lower portion of" said reservoir and the cup adjacent the sight tube.

In testimony whereof I allix my signature in presence of two witnesses.
